disgusting service

I own an A1 sline , automatic , going for a new clutch for a second time, but someone forgot to order the part . Black box was replaced last year and I had to pay for my own car hire!! No phone call no nothing . Will never purchase another audi . Top end brand? I did not spend all that money on a reliable brand to be let down every year by some engine or computer failure. I wonder if I will even get a response ?
